lIvI/ENToH Arron/vm frame E disposed upon the lower horizontal portions D2 of the block D, being secured thereto by means of screws or like fastening members E3 as clearly seen in Fig. 6.

Adjacent each of its ends, the lower horizontal portion D2 of the swinging frame, is provided with a cross piece B5 supporting adjacent its opposite ends, upwardly projecting rollers B, which when the parts are assembled project upwardly through the laterally slotted openings E2 of the base E of the berth-frame E before described, in order to support the weight of the berth itself, which berth to this end has a lower plate or the like F, seen particularly in Figs. 2 and 6, which as shown in Fig. 5, has a transverse track -F adjacent each end provided with grooves F2 which receive the rollers B6. The berth may, in addition to its lower plate F, include a spring F3 and a mattress F4 as best seen in Figs. 2 and 6, and if so desired the track F ma be formed directly upon the spring F3. hus during swinging movement of the frame including the horizontal portion B, which in the use of the berth constitutes a rack for the reception of the occupants apparel, luggage and the like, as indicated in Fig. l, moves the block D upon its pivot bolt D', swinging the latter in a degree considerably reduced as compared to the extent of swinging movement of the swinging frame itself, the berthframe E, secured to the horizontal extensions D2 of these blocks, following the movements of the blocks. At the same time, the weight of the occupant of the berth lying directly thereon, is supported from the swinging frame through the rollers BG, with respect to which the berth has movement within the limits of slots E2 so that the blocks D are relieved of all unnecessary strain, permitting ready and free movements thereof, under the guidance of the swinging frame.

I am thus enabled to rovide a berth for use on ship-board capable of maintaining a level position at all times, and the movement of which will be ready and free under all conditions and of considerably less extent than the swinging or tilting movements of the parts utilized to actuate the same and the stationary parts of the ship.

As before stated, the upright end supports A which are rigid in their nature, may be either portions of thev state-room walls, or in the nature of separate uprights attachable either at their lower ends to the state-room ioor, or at their sides to the state-room wall, and in this latter form as well as where constituted by a portion of the state-room walls,

I prefer that the supports be boxed in, by

the provision of front plates A detachably held to cover the upright end portions of the swinging frame, and the supporting and tilting blocks C and D, and in this way conceal from view practically all of the operating parts.

I claim:

l. In a self-leveling berth, the combination of a swinging frame having guide openings, pivoted supports disposed within said guide openings and actuated in their pivotal movements by the said swinging frame, a berth, and a berth-frame in which the berth is disposed, supported by and movable with, said pivoted support. p 2'. In a self-leveling berth, the combination of a swinging frame having guide openings, pivoted supports disposed within said guide openings and actuated in their pivotal movements by the said swinging frame, a berth movable with respect to, and supported by, said swinging frame, and a berth-frame in which the berth is disposed and with which it is movable, supported by and movable with said pivoted supports.

3. In a self-leveling berth, the combination of a swinging frame, pivoted supports actuated in their pivotal movement by the said swinging frame, a berth frame supported by and movable with said pivoted supports, and provided with slots, rollers carried by the swinging frame and projecting upwardly through the said slots of the .berth-frame, and a berth disposed within and movable with said berth-frame, and in Contact with and supported by, said rollers.

4. In a self-leveling berth, a swinging frame including upright end portions having rectangular slots, blocks disposed Within said slots and of substantially reduced width as compared to that of said slots, each of said blocks having one edge in engagement with one wall of its slot whereby to control the pivotal movement of the blocks on swinging movement of the frame, a berth-frame secured to, and supported by, said blocks, and a berth disposed within, and movable with, said berth-frame.

5. In a self-leveling berth, the combination of a swinging frame, pivoted supports actuated in their pivotal movement by the said swinging frame a berth frame supported by and movable with said pivoted supports, and provided with slots, rollers carried bythe swinging frame and projectingy upwardly through the said slots of the berth-frame, and a berth disposed within and movable with said berth-frame and in contact with and supported by said rollers, said berth including grooved transverse tracks receiving the said rollers.

6. In a self-leveling berth, a swinging frame including upright end portions having rectangular slots, blocks disposed within said slots and of substantially reduced width as compared to that of the slots, each of said blocks having an angular extension and having one edge thereof in engagement with one wall of its slot whereby to control the piv- 130 cured t andspportedf'byfth'said angular f' n portions of-ysidzf,blQkSnd provided-with OBERT HA s1ots,` rollers y` 3a`1f1``iedfby],the Vsaid., swinging Witnesses: v f j :L frame andprojectingupwadlyjthrough said F.
